GUN SIGHT.

Application filed October 18, 1924. Serial No. 744,456.

My present invention has reference to improvements in sights for firearms An object is to provide a sight which may be rotatably adjusted for accurate aiming when firing at different distances.

Another object is to provide a sight which may be attached to any firearm without changing the construction of the same.

With the above and other objects in view the invention resides in the construction, combination and operative association of parts such as is disclosed by the drawings which accompany and which form part of this application.

In the drawings Figure 1 is a view of the barrel of a firearm provided with sights in accordance with this invention.

Figure 2 is a sectional view approximately on the line 2-2 of Figure 1.

Figure 3 is a sectional view approximately on the line 33 of Figure 2.

Figure 4 is a. plan view of a peep sight employed on the rear of the barrel of the firearm.

Both the front and rear sights comprise a similarly constructed base, in the nature of a metal block 1. Each base, at the bottom thereof, has its sides formed with angle projections in the nature of flanges 2, and these flanges are inserted in dove-tailed grooves arranged transversely adjacent the front and rear of the firearm barrel 3.

The base 1 has its sides rounded toward its top and is provided, from its said top with a transverse notch. The notch is formed nearer the inner than the outer side of the base, so that the inner arms 4 are of a less thickness than the outer arms 5.

Received in the notch 6 of each of the base members 1 there is the body portion of the sights. The body portion of each sight is centrally formed with a. round opening and screwed through an opening in each of the arms 4 there is an enlarged threaded and kerfed end 7 of a screw member. The screw member has its central portion 8 smooth, the non-threaded portion having a reduced threaded extension 9 which is screwed in an opening in the arm 5 of the base. Arranged on the portion 8 of the screw for contacting engagement with one side of the body of the sight, to force the latter against the arm 5 of the said base, there is a spring washer 10.

The side of the sight body forced against the arm 5 of the base is provided with right angularly disposed circumferentially arranged depressions 11, any one of which is designed to be engaged by the end of a screw 12 having a milled head 13, the said screw being threaded through an opening in the arm 5.

The body of the sight at the front end of the firearm is formed with right angularly extending arms 14 respectively, the said arms being of different lengths and each terminating in a head of a different shape or contour. The body of the sight employed at the back of the firearm is provided with a pair of right angularly disposed peep openings 15, and with right angularly disposed notches 16. The width of the notch is varied and the inner wall of each of the said notches is formed with a V-shaped groove 17, one of the grooves being of a greater depth than the other.

By manipulating the screw 12 to withdraw the same from the notch 11 in the body of the sights, the said sights may be revolved upon their pivot bolts to arrange the proper sight at the top of the base 1. The screw or bolt member 12 is then brought to engage in the corresponding notch 11. The spring washer 10 serves to hold the sight from accidental turning before screw 12 is turned home.

The base 1 has its sides provided with oppositely arranged depressions to receive therein the inwardly directed ends 18 on the arms 19 of a guard. The guard is constructed from a single piece of spring metal and is rounded, as at 20.

The rounded portion 20 is extended above the sight.

The revoluble sight, as disclosed in Figure 3, may have passed through the openings in the outer ends of the arms thereof pintles 21 having heads 22 that provide the sights proper. In deer hunting in dark woods, either gold or ivory sights 22 are employed and the washer 10 permits of the sights being turned on the pivot 8 without danger of the heads 22 contacting with the inner faces of the arm 4. Also, if desired, the base 1 may be and preferably is grooved, as indicated by the dotted lines in Figure 2, for the reception of the arm 19 of the guard.

Having described the invention, I claim 1. A sight for firearms including a base which is notched at the top thereof, a sight body in the notch, means pivotally securing the sight body in the notch, spring means influencing the sight body against one Wall of the notch, said body having sights arranged about its periphery and having its face opposite that contacted by the spring means provided with depressions in a line with the respective sights, and an element threaded through the base to engage in one of the said depressions.

2. A sight for firearms including a base fixed on the barrel oi the firearm, said base having its sides rounded inwardly to its top and its said top notched transversely to a point away from the center of said base, a removable pivot passing through the arms provided at the opposite sides of the notch,

a sight having its body journaled on the pivot, spring means on the pivot influencing the sight toward one of the arms of the base, said sight body having sights arranged upon its periphery and having its face opposite that engaged by the spring means provided with spaced circun1ferentially arranged notches disposed one in a line with the respective sights, and a bolt member screwed through the second arm of the base and designed to be received in one of the notches.

In testimony whereof I afiix my signature.
